Thanks for trying the demo! Haha, I'm glad you like the MC's design and the two lady characters :). Those girls don't get a lot of attention so it's nice to see someone is a fan of them, aha. And it's interesting to hear what characters you think would make a nice couple :3.
Can you tell us when you downloaded the demo? We very recently uploaded a new build to fix that error. If you delete the version you have and download it again that problem shouldn't be there anymore.
